Pros:

-Great atmosphere
-Fun and intresting gameplay, (The dark rooms and the sewers were my favorite)
-I found that the levels were very well designed
-Cool hidden areas

Cons:

-On the final level, the game decided to not respawn Francis, ever. Not sure what the problem with that was.
-Also on the final level, (only level we had problems with) the second wall could not be destroyed, there was no way we could place any C4. If this is some stupid user error I will remove this.

Conclusion:

The only negatives I could find were the bugs that we ran into, I will definetly try it again another time, and also when updates are released. Most of these "cons" I see in the reviews seem 100% wrong to me, but I guess it's just an opinion. As bugs stand, I'd give this a 7.5, but without I would give this between a 9 and 9.5
(Figured it out and feel stupid, although I'm not sure if I heard him saying to clear the roadblocks first. Probably though, that or my friend was talking too much I couldn't hear)
